libKCD2

Reverse-engineered headers and runtime library for Kingdom Come: Deliverance 2 (CryEngine 3 + Warhorse modules). Includes KCSE (Kingdom Come Script Extender) — an SKSE-style native plugin framework.

This is a hobby project. Not every RE'd member is guaranteed correct — verify before use. Contributions welcome.

Build Dependencies

• spdlog
• Visual Studio 2022+
  • Desktop development with C++
• CMake 3.15+
• vcpkg

End User Dependencies

• Kingdom Come: Deliverance 2

Notes

• libKCD2 targets game version 1.5.6. CryEngine's interfuscator shuffles vtable order in release builds — SDK headers cannot be used for direct virtual calls across versions.

Developing a KCSE Plugin

1. Create your plugin repo under Projects/ (or add it as a submodule):

   Projects/MyPlugin/
   ├── .buildenv/
   │   └── CMakeLists.txt
   └── src/
       └── plugin.cpp
   

2. Minimal CMakeLists.txt:

   project(MyPlugin LANGUAGES CXX)
   
   file(GLOB_RECURSE PLUGIN_SOURCES "${CMAKE_CURRENT_SOURCE_DIR}/../src/*.cpp")
   add_library(MyPlugin SHARED ${PLUGIN_SOURCES})
   
   target_precompile_headers(MyPlugin PRIVATE "${RE_BUILDENV}/PCH.h")
   target_compile_definitions(MyPlugin PRIVATE _ITERATOR_DEBUG_LEVEL=0 WIN32_LEAN_AND_MEAN NOMINMAX)
   target_compile_options(MyPlugin PRIVATE /utf-8 /W4 /wd4819 /wd4100)
   target_include_directories(MyPlugin PRIVATE
       ${RE_ROOT}/include ${RE_ROOT}/include/CryEngine/CryCommon ${CMAKE_CURRENT_SOURCE_DIR}/../src)
   target_link_libraries(MyPlugin PRIVATE kcd_re spdlog::spdlog)

3. Minimal plugin.cpp:

   #include "KCSE/KCSEAPI.h"
   
   KCSE_PLUGIN_INFO("MyPlugin", "Author", 1);
   
   KCSE_PLUGIN_LOAD(kcse)
   {
       return true;
   }

Any subproject with a .buildenv/CMakeLists.txt is auto-discovered by the root build.
